23.(24)Apex of abdomen in ? 6-setose parallelomorphus-gvoxiip. 



24. (23) Apex of abdomen in 9 4-setose. 



25. (26)Elytra with crenulate striae, third interstice bearing more than two 



setiferous punctures australis-group. 



26.(25)Elytra with simple striae (only in N. triplogenioides crenulate), third 



interstice bipunctate (in N. dyscoloides often with three or four 



punctures) Jcingi-group. 



27.(22)Posterior tarsi short, first joint not longer tMan two succeeding 



joints together lateralis-group. 



28.(18)Elytra with striae 1-4 deeply impressed, striae 5-7 obsolete except at 



apex mediostdcatus-group. 



29.(18)Elytra lightly striate, interstices flat and (including eighth) not 



convex at apex chalybeus-group. 



30. (l)Episterna of metasternum elongate lesueuri- group. 



The cupricolor-group. 



Prothorax with basal angles rectangular; border widely re- 

 flexed posteriorly, and passing round angle and on to base as far as 

 lateral basal impressions. Elytra with humeral angles rounded; 

 interstices depressed, third 5-punctate, eighth narrower than 

 ninth. Intercoxal declivity of presternum wide, flat, sparsely 

 setose. Tarsi with joints substriate on upper surface; first joint 

 of four posterior tarsi strongly costate on external side, costa 

 spinulose beneath; fifth joint glabrous beneath. 



I have felt compelled to constitute a separate group for LA 7 ". 

 cupricolor SI., which is probably a primitive form, showing some 

 affinities towards Bhabdotus, and also to the eques-grouip of 

 Notonomus. It is the only species of Notonomus with the point 

 of the presternum setose; these setae are about six in number, the 

 two lower ones being well down on the face of the intercoxal 

 declivity, looking at the insect when laid on its back. Only the 

 male is known; it will be interesting to find whether the apex of 

 the abdomen in the female has six se£se, as in the eques-group, or 

 not. 



The e^es-group. 



Prothorax with posterior marginal puncture not at basal angle, 

 nor on border. Elytra with basal border more or less dentate at 

 humeral angles, third interstice with more than two punctures. 

 Apical ventral segment in <J 2-punctate, in £ 6-punctate. Tarsi
